This invention relates to recoil pads for guns.

An object of the invention is the provision of a pad formed entirely of resilient material, such as rubber or some composition having elastic qualn ities, in which transverse ribs connect a top and bottom together with said ribs being thickened intermediate the ends thereof so that when a rearward thrust is exerted by a gun the pad will be compressed and then extended to eliminate shocks to the muscles of the operator of the gun.

Another object of the invention is the provision of a recoil pad for guns` which is formed of resilient and elastic materials in which a top and bottom portion are connected together by transverse ribs having thickened portions intermediate their ends, while the ribs generally are relatively thin so that when a thrust is exerted by the gun on the pad which engages the shoulders of the operator the pad will be compressed to some extent along a longitudinal central line while the outer longitudinal edges will be compresse-d to a greater extent thereby protecting the muscles oi the operator against injury.

f A further object of the invention is the provision of a recoil pad for guns formed of elastic and resilient materials which will be in contact with that portion of the body of the operator adjacent the shoulder, the portions of the pad at each side of a longitudinal central line being compressible to a greater extent to protect those parts of the body where the longitudinal outer edges of the pad come in contact with the body.

This invention will be best understood from a consideration of the following detailed description, in forming a part of the specification; nevertheless, it is to be understood that the invention is not conned to the disclosure, being susceptible of such changes and modications as denne no material departure from the salient features of the invention as expressed in the appended claims.

Figure 6 is a vertical section taken along the line 6 5 of Figure 5.

view of the accompanying drawing Lil 'Figure 7 is a transverse horizontal section taken along the line -'l of Figure 5.

Referring more particularly to Figs. l to 4.,`in' elusive, It designates' a top or inner portion which is curved transversely as shown more particularly in Fig. 3, while ii designates a bottom or inner portion which is cemented or vulcanized to a base member i2 that is secured to the outer end of the stock of the gun. The outer surface of the member it is of a configuration which cor` responds to the usual design of the outer'en'd of the gun stock.

The portion il is relatively flat at its opposite faces and has substantially the same thickness throughout and is spaced from the member i'by spaced transverse ribs generally designatedfby the numeral i3.

it will be noted from Figure 2 that the trans*- verse ribs i3 are relatively thin, but tlieLcene trol portions, as shown at l, are thickened "D0 provide greater resistance along a longitudinal line upon the thrust of .the lgun during firing.'

rEhe thickened portions are approximately. elliptical in pian view. The op-posite'endscf fthe elliptical portions merge into the thin lwalls.: of the outer ends of the. ribs.v .The spaced' .ribs i3 have narrow passages therebetween, as shown at l5, which open through 'the side walls4 iii of tnepad. i .i

The opposite ends or the pad 'areclosed bythicli walls Il and I3, and the ribs I3 arid the thickened portions are located between said walls. The outer edges of the walls I'l and IS are curved to conform to the curvature of the ends of the pad.

A plurality of pairs of spaced ribs, indicated by the numerais 2E, 2i and 22 run longitudinally of the pad and upon one side of the thickened portions il. Thus, in effect these ribs enclose the thickened portions. It will be noted that the ribs 2i, 22 are located in staggered relation with the pairs of ribs 2@ and that all of the ribs re curved to conform to the curvature of the adjacent side edge of the pad.

The pad is formed of some elastic and resilient f material such as rubber or a composition having resilient and elastic qualities. The materials are cast in a form so that the ribs i3, the thickened portions lit, ribs 2G to 22, inclusive, the walls il, i3 and the members lil and il are integrally connected together.

The members lil and ll are provided with horizontal passages E5 through which a screw is passed. The head of the screw, however, is adapted to engage a seat 26 at the inner end of a passage 2l formed in the member l2 and in alinement with the passage 25 for connecting the pad to the outer end of the stock of a gun.

Referring more particularly to Figs. to 7, inclusive, it will be seen that the pad illustrated is similar in many respects to the pad shown in Figs. 1 to 4, inclusive, except that the ribs |3a are bent intermediate their ends so that the ends are inclined toward each other from the thickened portions Ma.

The thickened portions are located at the apex of the angle formed by the inclined rib sections and are of less capacity than the thickened portions H shown in Fig. 2.

Pairs of longitudinal ribs in a modied form are substantially the same as those shown in Fig. 2 and, therefore, the same reference numerals are applied. It will be noted that all of the other elements of the modified form are substantially the same as similarly placed elements of the form shown in Figs. 1 and 4, and, therefore. the same reference numerals are applied thereto except end portions l'la and |8a. The only difference between the end walls is that the inner edges of these Walls conform to the partlcular shape of the bent ribs. The results obtained by both types of cushions are subst-antially the same. p

The pair of longitudinal ribs 30 in both forms run the full length of the pad between the ends I1, IB and l 1a, IBa, although the same type of pair of 4staggered ribs 20, 2i and 22 may be cmployed at both sides of the pad.

When a thrust is exerted by the gun when being red the lcushion is compressed but it readily returnsto `normal condition when the pressureis released. The pressure exerted by the gun is substantially constant on all points of the pad `since the flexibility of the pad varies from vthe side edges to the central longitudinal line .passing through the thickened portions of the ribs.

This central longitudinal line of the pad which contacts that part of the human body adjacent the shoulderk receives the full thrust while the portions of the pad at each side of said line which have a greater degree of flexibility and resilience aid in dissipating the force of the thrust so that the force of the impact is tapered off from the central line through the more compressible portions of the ribs at the sides of the pad` Thus the greater degree of compressibility of the longitudinal regions of the pad at each side of the central line eliminates any danger of the edges of the gun stock from bruising the contacted portion of the body of the operator of the gun.

A recoil pad for guns comprising an elongated member formed of resilient material and having a top and bottom, transverse ribs joining the top and bottom and forming a resilient cushion between the top and bottom, the central portions of the ribs being thickened, and pairs of longitudinal ribs joining the top and bottom adjacent the side edges of the pad, one pair of the longitudinal ribs at one side of a longitudinal central line being closer to said line than the other pairs of ribs on the same side of the line.
